Effects of Weaving Density on Curing Duration and Quality of Ganyan 157 Tobacco Leaves at Different Leaf Positions
摘要
Abstract
To address the issue of optimal leaf arrangement density for curing Ganyan 157 in the tobacco-growing regions of Jiangxi under rainy ecological conditions,this study used lower leaves(3rd-5th leaf position),middle leaves(8th-10th leaf position),and upper leaves(15th-17th leaf position)as materials.Different leaf arrangement densities were set to systematically analyze their effects on tobacco leaf curing quality.The results showed that leaf arrangement density significantly influenced curing duration and tobacco leaf quality,with distinct effects depending on leaf position.As the number of leaves per stick increased,curing time decreased(by 9 hours for lower leaves and 5.5-8 hours for middle and upper leaves),but excessively rapid curing was detrimental to quality formation.For lower leaves,the X120 treatment(120 leaves/stick,320 sticks/kiln)achieved the highest proportion of orange-yellow leaves(52.65%)and the lowest proportion of greenish leaves(10.41%),along with the highest sensory score(72.4).For middle leaves,the C130 treatment(130 leaves/stick,340 sticks/kiln)exhibited a low ash rate,optimal oil content and color intensity,and the highest aroma score(16.5).For upper leaves,the B140 treatment(140 leaves/stick,350 sticks/kiln)yielded the highest orange-yellow leaf rate(64.16%)and sensory score(73.5).Leaf arrangement density had no significant effect on most chemical components of the tobacco leaves,but the X120 treatment significantly reduced starch content in lower leaves.The total plastid pigment and aroma substance contents followed the order:lower leaves>middle leaves>upper leaves.The X140 treatment(140 leaves/stick,320 sticks/kiln)significantly promoted pigment degradation in lower leaves,resulting in the highest total aroma substance content,while the B120 treatment(120 leaves/stick,408 sticks/kiln)favored the accumulation of phenylalanine degradation products in upper leaves.Thus,the optimal leaf arrangement parameters for Ganyan 157 were significantly lower than those for traditional varieties K326 and Yunyan 87.Specifically,120 leaves/stick for lower leaves,130 leaves/stick for middle leaves,and 140 leaves/stick for upper leaves can balance curing efficiency,appearance quality,and sensory quality.The result can provide technical support for curing this high-quality tobacco strain in rainy ecological regions.关键词
